~~NOTOC~~
====== Welcome! ======

Welcome to my personal website. I'm Paweł Redman, known online as "enneract," a programmer and a former Optics student. This wiki serves both as my personal blog and a library for interesting things, relating to science and programming, that I've bothered to write down.

I finished my Bachelor of Science Degree at the Wrocław University of Science and Technology in February 2020 . My thesis is available [[engineers_thesis|here]] (in Polish only).


===== Programming =====

I'm currently employed by Nokia as a hard real-time software engineer, working on layer 1 4G and 5G NR products.

Active open source projects:

  * [[https://zittrig.eu|Zittrig]] – an online community primarily centered around Tremulous and the Der Bunker server.
    * [[https://github.com/enneract/AA-QVM|AA-QVM]] – game logic for the Der Bunker Tremulous server.
    * [[schachtmeister2|]] – a daemon that looks people up in WHOIS and reverse DNS to fight ban evasion.

2020

  * [[https://github.com/WUST-FOG/gnlse-python|gnlse-python]] – a Python package for solving a generalized Schrödinger equation to model non-linear optics in fibers.
  * [[polarization|]] – a tool for visualizing and learning about polarization of light.
  * **[[gsoc2020]]** – implementing new spectral upsamping methods and color quality metrics in [[https://github.com/colour-science/colour|Colour]], a Python package for color science.

2016–2019

  * [[minitrem]] – a simple 2D strategy game, inspired by Tremulous.
  * [[https://redman.xyz/git/mapcat|mapcat]] – a tool for concatenating Tremulous map files.
  * [[https://unvanquished.net/|Unvanquished]] – an open source shooter (a remake of Tremulous) that I've contributed some code and assets to
  * [[https://github.com/mtiusane/new-edge|New EDGE]] – a game modification for [[Tremulous]].

2015 and older
  * [[cem|Cem]] – my first FDTD wave optics simulator.
  * [[ray|Ray]] – my first path tracer.
  * [[https://redman.xyz/git/cuboid|Cuboid]] – another, older mod for [[Tremulous]].

===== Computer graphics and photography =====

I've also worked on a few music videos for local rap artists:
  * [[https://www.youtube.com/watch?v=scImbwl3awc|Nosi - Minuta Ciszy]] (direction, camera, editing)
  * [[https://www.youtube.com/watch?v=5S0QNBOQcQU|Nosi - Sennik]] (direction, camera, editing)
  * [[https://www.youtube.com/watch?v=-d4RZ7dOukc|Danio x Tomo - NOWY KLASYK]] (camera, editing)
